AWR1642: How many free SPI flash space left after burning the firmware

Hi,

Now we are using Uniflash to burn the firmware of radar chip on SPI. Is the size of the AWR1642 bin file the total SPI flash the firmware occupied? Or Uniflash will add some header so the size will be bigger than the bin file? If yes, how many bytes are added?

How about AWR1443? As we need to burn two bin files to spi flash? How many free SPI flash space left after burning these two bin files?

Customer wants to use SPI flash to store some own data and need to know which part of spi flash they can use after burning the firmware.

Thanks,

    Hi Chris,

    On AWR1642 devices, the size of the multi-core image (MetaImage) is the total size occupied in the Serial Data Flash.

    On current ES2.0 AWR1443 devices, the initial 256 KB of memory is allocated for device firmware. So, the MSS application image would reside at the SDF offset 0x40000. Hence, the SDF is occupied upto (256 KB + Size of MSS application image). The region beyond this is free. You may also refer to the AWR1243 bootloader flow doc http://www.ti.com/lit/an/swra561/swra561.pdf

    So, in both cases, the customer information may reside at the SDF sector following the last sector used up by the image.

    Best regards,

    Naveen
